Influence of different calcic antagonists on the Caco-2 cell monolayer integrity or "TEER, a measurement of toxicity?".
Article in European journal of drug metabolism and pharmacokinetics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The purpose of this work was to investigate the interest of the TEER measurement, a quite simple measure, as an evaluation of toxicity, in function of time and level of drug in the experimental medium, for different anticalcic agents. The extend of the increase and decrease of TEER, was evaluated by measuring the TEERmax and calculating the TEER50 respectively. Three groups of compounds could be therefore considered. The first, characterized by a quite short period of TEER increase, followed by an extremely rapid decrease (high values of TEER50), included perhexiline and prenylamine. The most toxic compounds, the second one, characterized by the smallest variations of TEER, included verapamil and diltiazem. This group was related with the less toxic compounds, the third group, represented by bepridil, characterized by dependant-dose TEERmax and TEER50. Therefore, the TEER measurement appeared as a quite simple approach of comparative toxicity of anticalcic agents.
